The map shows 3172 hydrometric stations, 1491 active and 1681 inactive, located on rivers and lakes across the country. All the stations on the map are situated in a drainage area of 200 square kilometres or more. For 1200 stations shown on the map, surface water level measurements are recorded...

Hydrology is the science concerned with the occurrence and distribution of water on and under the earth. Meteorology is the science dealing with the atmosphere and the movement of water, both as vapour and as liquid, in the air. Both sciences are concerned with the hydrologic cycle - the...

Wetlands mainly occur low in the landscape and form areas of groundwater discharge. This aids in the accumulation and composition of peat, as water moves slowly in wetlands. Local topography and sediment characteristics, such as an underlying low-permeability clay layer, can lead to wetlands...

Wetlands are lands where water saturation is the dominant factor. Wetlands occupy about 18% of Canada, and Canada has about 25% of the world’s wetlands. Wetlands foster the growth of hydrophytic vegetation and other biological activities such as the sustenance of large numbers of waterfowl,...

Wetlands are areas characterized by relatively shallow water. These areas play an extremely important role in Canada's ecology. Canada has one of the largest areas in the world with wetlands covering more than 1.2 million square kilometres. They occur across most of the country, and their...

Contained within the 5th Edition (1978 to 1995) of the National Atlas of Canada is a map that shows occurrence of wetlands throughout Canada, using five percentage cover classes. Table gives estimated wetland area by province and territory.

Contained within the Atlas of Canada Poster Map Series, is a poster which outlines the nature of wetlands, using photos and text to describe various types. A further set of photos and text describes the importance of wetlands, and the pressures on wetlands from human activities. The central map...

Wetlands are lands permanently or temporarily submerged or permeated by water, and characterized by plants adapted to saturated-soil conditions. Wetlands are the only ecosystem designated for conservation by international convention because they absorb the impact of hydrologic events, filter...

Contained within the 4th Edition (1974) of the Atlas of Canada is a map that shows the area of wetlands as a percentage of grid-units, 10 000 square kilometres in area. The term, wetlands, as used on this map, refers to areas represented on the 1:250 000 scale maps of the National Topographical...
